Primary bone hemangiosarcoma involving the 4th digit in a Siberian Husky dog

摘要

An 11-year-old female spayed Siberian Husky was presented with a left hind, swollen, bleeding mass involving digit 4. Radiographs revealed osteolytic lesions involving the distal phalanx (P3) and part of the middle phalanx (P2). Digit amputation was performed; histopathology was consistent with hemangiosarcoma. Although no signs of systemic involvement were detected around the time of amputation, the patient was euthanised 47 days later due to regional and distant metastasis.
